LAST UPDATEDLake Lonsdale is a large, shallow reservoir on the Mt William Creek. It fills from its own catchment and is reliant on natural inflows. Although the catchment can be a substantial producer of water during wet years because of its very large area, it isn't reliable during times of drought. Given its relatively shallow depth, the lake also has high evaporation losses over summer months.
Since the introduction of the Wimmera Mallee Pipeline, the lake is no longer used by GWMWater for domestic or stock water supply, however it's still a key source of water for the environment. Lake Lonsdale also has an important role in the community as a recreational lake in the Stawell area, hosting a number of activities on its northern side, such as boating, fishing, swimming, camping and water skiing.
Be sure to play it safe around water.
Read our information signage before entering the water.
